Login to the box and run

Code:

sudo apt-get autoclean && sudo apt-get clean

find /var/log -type f -delete

find /var/log -type f -name "*.gz" -delete

That should recover some space

Then once that is done reboot.

Once rebooted download texturecache.py http://forum.kodi.tv/showthread.php?tid=158373

Login again into box execute texturecache.py with P option then with R option then with Xd option

That should clear you all the crud and wast of textures that are dead from your Thumbnails folder and recover at least a few GB space from there.

Code:

python ./texturecache.py P; python ./texturecache.py R; python ./texturecache.py Xd
